Hi, I am developing a SSL client that will do a simple request to a SSL server and wait for the response. The SSL handshake and the writing goes OK but I can't READ data from the socket. I turned on the debug of java.net.ssl and got the following:

[..] main, READ: TLSv1 Change Cipher Spec, length = 1 [Raw read]: length = 5 0000: 16 03 01 00 20 .... [Raw read]: length = 32 [..] main, READ: TLSv1 Handshake, length = 32 Padded plaintext after DECRYPTION: len = 32 [..] * Finished verify_data: { 29, 1, 139, 226, 25, 1, 96, 254, 176, 51, 206, 35 }


%% Didn't cache non-resumable client session: [Session-1, SSL_RSA_WITH_RC4_128_MD5] [read] MD5 and SHA1 hashes: len = 16 0000: 14 00 00 0C 1D 01 8B E2 19 01 60 FE B0 33 CE 23 ..........`..3.# Padded plaintext before ENCRYPTION: len = 70 [..] a.j.y. main, WRITE: TLSv1 Application Data, length = 70 [Raw write]: length = 75 [..] Padded plaintext before ENCRYPTION: len = 70 [..] main, WRITE: TLSv1 Application Data, length = 70 [Raw write]: length = 75 [..] main, received EOFException: ignored main, called closeInternal(false) main, SEND TLSv1 ALERT: warning, description = close_notify Padded plaintext before ENCRYPTION: len = 18 [..] main, WRITE: TLSv1 Alert, length = 18 [Raw write]: length = 23 [..] main, called close() main, called closeInternal(true) main, called close() main, called closeInternal(true)

The [..] are the certificate chain.

Here is a code snippet:

try { System.setProperty("javax.net.debug","all"); /* * Set up a key manager for client authentication * if asked by the server. Use the implementation's * default TrustStore and secureRandom routines. */ SSLSocketFactory factory = null; try { SSLContext ctx; KeyManagerFactory kmf; KeyStore ks; char[] passphrase = "importkey".toCharArray();

        ctx = SSLContext.getInstance("TLS");
        kmf = KeyManagerFactory.getInstance("SunX509");
        ks = KeyStore.getInstance("JKS");

        ks.load(new FileInputStream("keystore.jks"), passphrase);

        kmf.init(ks, passphrase);
        ctx.init(kmf.getKeyManagers(), null, null);

        factory = ctx.getSocketFactory();
        } catch (Exception e) {
            throw new IOException(e.getMessage());
        }

        SSLSocket socket = (SSLSocket)factory.createSocket("server ip", 9999);

        /*
         * send http request
         *
         * See SSLSocketClient.java for more information about why
         * there is a forced handshake here when using PrintWriters.
         */
        SSLSession session = socket.getSession();

        [build query]

        byte[] buff = query.toWire();

        out.write(buff);
        out.flush();

        InputStream input = socket.getInputStream();

        int readBytes = -1;
        int randomLength = 1024;
        byte[] buffer  = new byte[randomLength];
        while((readBytes = input.read(buffer, 0, randomLength)) != -1) {
            LOG.debug("Read: " + new String(buffer));
        }
        input.close();
        socket.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

I can write multiple times and I don't get any error but the EOFException happens on the first read.

Am I doing something wrong with the socket or with the SSL authentication?

Thank you.
